Review on Smileactives Advanced Teeth Whitening Pen with Tooth Whitening Gel - Vanilla Mint Duo Pack, Travel Size 0.11 Ounce Each - Achieve Whiter Teeth! by Roberta Johnson

I bought a mouthguard/teeth whitener (Opalescense) from my dentist. I did a charcoal cleaning. Tried strips and ultraviolet. You name it, I've tried. Well, to be honest, my teeth are NOT that bad; However, I was hoping for that "dazzling" snow-white smile! Well, these pens work! THEY REALLY WORK! They're fast, light, and you'll see the difference in no time! And while I'm not claiming to have a "gorgeous" smile, they're definitely white (pass the "cloth test" of white). I'm more than happy with the results - an added bonus: no gum irritation and no tooth sensitivity. I just ordered two more pens! This is now my favorite product!
